IMPROVEMENT IN LEATHER-DRESSING MACHINERY.

Specification forming part of Letters Patent No. 16] ,046, dated March23, 1876; application filed February 6, 1875.

To all whom it may concern:

Be it known that I, NORMAN OLMSTEAD LOUNSBERRY, of Wilmington, in thecounty of New Castle and State of Delaware, have invented a new andvaluable Improvement in Glazing or Polishing Leather; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the'same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a front elevation of myglazing-machine. Fig. 2 is a plan view of the same and Figs. 3, 4, 5, 6,and 7 are detail views.

This invention has relation to means for polishing leather; and itconsists, mainly, in a rotating beam carrying the polishing-agates, orother equivalent polishers, in combination with vyielding beds or tablesof peculiar construction, on which the skins are applied, and upon whichthey are polished, as will be understood from the following description:

In the annexed drawings, A A designate two uprights, which rise from abase-frame, B, and which have rigidly secured to them, near their upperends, a horizontal beam, (3, which affords, at the middle of its length,a bearing for the upper journal of a vertical shaft, D. The lower end ofthis shaft D is stepped in a bearing-box, a, which is made fast to across-beam of the base-frame B.

The shaft D may be extended up to the ceiling of the room in which themachine is located, and rotated by means of beveled wheels and anoverhead line-shaftin g.

The drawing represents the shaft D with a bevel-wheel, b, keyed on it,which gears with a wheel, I), keyed on a shaft, E, which latter isjournaled in a bracket, 0, and a box, 0. When shaft E is rotated, theshaft D will receive rotation faster or slower, as the circumstances ofthe case may require. Gr Gr designate two frames, which are located onopposite sides of, and equidistant from, the vertical shaft D, and whichare composed, respectively, of two uprights rising from the base-frameB, and a horizontal bar, 01, which is secured to the said uprights. Tothe bar at of each frame G two springs, s s, are secured, the upper freeends of which sustain a table, H, on which is secured a polishing-bed,f, the extremities of which are beveled down flush with the table H.Each table H, with its polishing-bed f is free to yield downwardly,resisted only by the force of the springs beneath it. The shaft D hassecured to it, below the wheels I) and b, a horizontal cross-head, J,the ends of which are equidistant from said shaft. The ends of this headJ have rigidly, but removably, secured to them flanged blocks 9 g, towhich are secured, by means of bolts and nuts and clamps j j, agates, orany other suitable polishing substance, which I designate by letters hh.

It is by the repeated passage of these agates over the leather, which isdrawn over the beds f, that the leather is polished, and it is obviousthat the work can be rapidly and economically performed by the meansdescribed.

The work-tables H H have bars c c permanently secured to them, the endsof which bars are notched and adapted to receive the slotted ends of theuprights of frame Gr, thereby keeping the tables in their places, butallowing them free vertical motion as the agates pass over them.

Having'thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The table H, having the slotted uprights Gr and springs S, incombination with the rotary cross-head J, carrying glazing-pieces h,substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
